RETORT -Filed Aug. 2'7, 1928 5 Sheets-Sheet 5 31a/vanto@ Patented June 10, 1930 UNITED STATES PATENT OFFICE WILLIAM F. RIEGER, OF SALT LAKE CITY, UTAH, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE STOKER MATIC CORPORATION, OF SALT LAKE CITY, UTAH, A CORPORATION OF 'UTAH RETORT Application filed August27, 1928. Serial No. 302,310.

M invention relates to retorts and has for its o ject to provide a new and efficient water cooled retort for furnaces, heating plants and boilers which will be economical to operate,

easily installed and which will last a long time in service.

A further object is to provide a retort which will not burn out from everheating and one which will eliminate the troublesome feature of clinkers freezing to the outer rim and clogging the tuyre openings and rendering combustion ofthe fuel difficult or impossible.

A still further object is to provide an air and water cooled retort for heating plants in which the tuyre openings are between the wat-er jackets.

These objects I accomplish with the device illustrated in the accompanying drawings in which similar numerals and letters of reference indicate like parts throughout theseveral views and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawings in which I have shown the best and most preferred manner of building my invention Figure 1 is a plan view of the retort with the furnace outlines in dotted lines. Figure 2 is a longitudinal section. Figure 3 is a transverse section. Figure 4 is a sectional View of a modified manner of building the water chamber and the tuyre openings therein. Figure 5 is a modified form of Figure 4. Figure 6 is a modification of the device showing the use of tubular water chambers. Figure 7 is a modification of Figure 6 with the side walls sloping. Figure 8 1s a modification of Figure 4 with the side walls shown sloping.- Figure 9 is a simplified manner -of building the entire retort with tuyre openings shown tapered. Figure 10 is a modification of Figure 8 but with each water jacket made separately and spaced from the next by a wall extension.

In the drawings I have shown the outline of body of the retort as B. The retort is made up of ya rectangular shaped body member B having water jackets 1 and 2 around the in- 3 of the retort forming the front side of the the furnace in dotted lines A, with the main l said ackets. Tuyre openings 4 are then cut through the face 3 between the two jackets 1 and 2, to allow passage of air therethrough. The tuyre openings may be rectangular in `cross section or any other shape desired for the furnace. In Figures 2, 3, 4, 8 and l0 the water jackets are shown as triangular shaped in cross section while those shown in Figures 6 and 7 are cylindrical and those in Figure 5 are square. The triangular jackets shown in `rFigures 2, 3, 4, 8 and 10 are'made Within the air chamber v5 and the front face of the air chamber is made up of the jackets spaced apart either by an integral wall extension as shown in Figure v10 or by welding a sheet of metal 6 across the space between the jackets and forming the tuyre openings therethrough as shown in Fig. 4. The cylindrical water jackets are spaced apart by a fiat sheet of metal 7 having the tuyre openings 4 cut therein, and the square Water jackets are spaced apart by the front face of the air chamber being made as the front face of the waterjackets. The air chamber C is made of four sides of sheet metal connected together with the top closed and air openings 5 therethrough or the top may be left off as shown in Figures 5, 6, 8, 9 an-d 10, and the sides extended upwardly to form part of the upper part of the air chamber 5. The chamber C and the air chamber 5 are in open communication and may be made integral with the water jackets therein. lBelow the water jackets and as a top side for the central portion of the air chamber C, I provide a curved semicircular sheet of metal 10 which is secured to the top of the air chamber at its sides and ends and constitutes the surface over which the fuel is introduced. The fuel screw 14 is mounted .in a cylindrical feed pipe 12 and sov forces the fuel inwardly over ,the sheet 10 The fuel is fed into the retort through the ner periphery thereof, and with thel inner face@ pipe 12 by the screw 11 and it is there ignited by the fuel already burning therein or by a nected with a source of water supply or with the boiler which the retort is heating and aid in the heating of the boiler by introducing the hot water or steam therein. The water jackets must have circulating water therein to keep them cool.

Having thus described my invention what 'I claim as new and desire to secure by Letters Patent is:

1.'In a furnace construction of the class desc'ribed, a retort having a pluralit of openings in the walls thereof, an air c amber having its circumscribing wall arranged in spaced relation to the retort walls, and Water cooling means projecting into the air chamber from the retort walls, said water cooling means defining water cooled air passages communicating with the openings in i described, a retort havin the retort walls and constituting cooling means for said openings and walls.

2. In a furnace construction of the class described, the combination of a retort, an air chamber surrounding the same and having its circumscribing wall arranged in spaced relation to the retort walls, said retort walls having a plurality of rows of o enl ings therein, and water conduits carrie by and extending about the said retort walls, said conduits defining air passages communicating with the openings 1n the retort walls and constituting cooling means for said passages and walls.

3. In a furnace construction of the class bottom and side walls, an enclosing air c amber extending around and beneath the retort and having its circumscribing wall arranged in spaced relation to the retort walls, and a pluralit of` cooling tubes formed on the side walls o the retort in spaced relation to each' other and projecting into the air chamber to define air passages therebetween, said side walls having tuyre openings therethrough intermediate thesaid cooling tubes in communication with the air passages defined by said cooling tubes.

4.A In a furnace construction of the class described, a retort having a plurality of rows of openings in the walls thereof, an air chamber surrounding the retort and having its Vcircumscribing wall arranged in spaced relation tothe retort walls, and water cooling means formed on said retort walls above and below the openings in said walls and extending into. the air chamber, said water cooling 4amarsi;

means defining water cooled air passages therebetween in communication with the said openings and constituting cooling means for the retort walls.

5. In a furnace construction of the class described, a retort, fuel feeding means therefor having a curved bottom, side walls extending upwardly therefrom, aA cooling jacket formed on the said walls at the top thereof, said walls having tuyre openings therein disposed adjacent to the cooling jacket, a second coolin jacket disposed on the said walls'below vt e first mentioned jacket and adjacent to the tuyre openings, an air chamber surrounding the retort and having its circumscribing wall extending downwardly from the first mentioned jacket in spaced relation to the retort and enclosing the second jacket, said jackets defining air passages therebetween in communication with the said tuyre openings in the side walls and constitutingl cooling means for said pas; sages and walls, and means for supplying air to the air chamber and tuyre openings.

In testimony whereof I have affixed my signature.

WILLIAM F. RIEGER.
